Description

Technical Field

[0001] The utility model relates to the technical field of fastening parts, and more specifically to a snap plastic tab with a movable hanging buckle. Background Art

[0002] A zipper generally includes a cloth tape, chain teeth, upper and lower stops, and a pull head. The pull head can be further divided into a pull head body and a tab movably arranged on the pull head body. Traditional tabs are generally made of metal materials and are rotatably arranged on the pull head body. Currently, on some clothes or luggage, many manufacturers use plastic materials to make the tab. The tab is generally processed into a long strip shape, and a female buckle with a fixed structure is arranged at one end of the tab. The female buckle remains stationary. When it is necessary to adjust the tightness, one end of the tab is inserted into the female buckle, and the tab is fixed on the female buckle to achieve the effect of adjusting the tightness. Existing plastic tabs usually only have the function of tightening, that is, after the tab is inserted into the female buckle, it can only be tightened forward and cannot be loosened backward, and cannot be flexibly adjusted, resulting in poor practicability. In addition, when the existing plastic tab needs to be loosened, a switch is usually arranged on the female buckle, but in some scenarios, the female buckle is hidden, which is not convenient to completely loosen the plastic tab through the female buckle. In response to this, the inventor proposes a snap plastic tab with a movable hanging buckle, which can simply and conveniently adjust the tightness of the plastic tab, and can be completely loosened on the plastic tab without moving the female buckle.

[0003] In order to improve the fastening degree of the plastic tab and enable it to better achieve the tightening effect, Chinese Patent (Authorized Publication No.: CN204561151U) discloses a new type of plastic tab. The utility model includes a long strip-shaped tab body, and a through hole is formed at one end of the tab body; a convex particle also protrudes on the tab body, and when the other end of the tab body bypasses the pull head body and then passes through the through hole, the convex particle is located in the formed knot. Compared with the prior art, the utility model has the characteristics of strong structural compactness and higher product quality by protruding a convex particle on the tab body and the convex particle being located in the formed knot when the other end of the tab body bypasses the pull head body and then passes through the through hole.

[0004] This solution still has some deficiencies in application. Since plastic tabs are often installed on backpacks or clothes as accessories for adjusting tightness, if they only have the tightening function and no loosening function, it is obvious that they cannot meet people's needs. At the same time, in some scenarios, a split structure is adopted, and the female buckle is hidden and cannot be touched. According to the prior art, it is not convenient to loosen the plastic tab, which brings great inconvenience to loosening the plastic tab. Therefore, it is necessary to improve the structure of the plastic tab so that it can not only flexibly adjust the tightness, but also unfasten the buckle through the plastic tab, overcome the above-mentioned limitations, and further improve the practicability of the plastic tab.
